Early Evolution of CMEs as Seen in Ly α and White Light by Future ASO-S/LST
Abstract
The Advanced Space-based Solar Observatory (ASO-S) mission is the first Chinese solar mission dedicated to study solar eruptions and their magnetism. Ly α solar telescope (LST) is one of the three payloads aboard ASO-S with its major goals to study coronal mass ejections (CMEs). It covers the observations from the solar disk to 2.5 solar radii in Ly α and white light. The design and current status of LST are introduced. Starting with the physical parameters derived from the 3D MHD simulations with SWMF/BATS-R-US code, we synthesize the Ly α and white light emissions from about 1.1 to 2.5 solar radii. The early evolution of CMEs and their related structures, e.g., CME-driven shock, streamers, are investigated and analyzed. Specific attentions will be paid to their expansion, thermal and density evolutions via our newly developed plasma diagnostic tools. We will also discuss the future possibilities of coordinated studies with theMulti Element Telescope for Imaging and Spectroscopy (METIS) coronagraph aboard Solar Orbiter.
